The utility model relates to a kind of in order to handle the air cleaner of dusty gas, belongs to the utensil that purifies air and use.
At present utensils such as the smoke exhaust ventilator that uses of people and ventilation fan are the swabbing action soil pick-up flue gas pollutants that relies on blower fan, and purification efficiency is low, and dusty gas must cause body inside and outside seriously polluted by cabinet and blower fan, clean also inconvenient.
The detergent power that the design the purpose of this utility model provides a kind of people's life and industrial and agricultural production use is strong, efficient is high and can prevent in the body and the contaminated jet suction of blower fan air engine.
The utility model is achieved through the following technical solutions.
First kind, soil pick-up nozzle crosswise jet scheme: comprise that jet leads jet pipe and soil pick-up nozzle, jet is led nozzle entry and is communicated with jet source generation utensil, jet is led jet pipe and is provided with the soil pick-up nozzle that is communicated with it, soil pick-up jet expansion direction is intersected successively mutually, and the soil pick-up nozzle intersects air-flow that forward injection converges successively and is the exhaust airstream of jet suction air engine.
Jet source generation utensil in this programme is meant blower fan, compressor, high pressure gas pipeline, high-pressure transfusion tube road etc.As required, the assembling such as machine, compressor, high pressure gas pipeline, high-pressure transfusion tube road that can follow the wind respectively of whole jet suction air engine is used, and provides pure air stream, vapor stream and the current etc. that have certain mechanical energy to satisfy the soil pick-up nozzle ejection to jet suction air engine respectively by these utensils.
Jet is led jet pipe can adopt different pipe shapes respectively, picture annular, arc, square, bend pipe, straight tube, also can adopt the combined pipe body that constitutes by these difform pipelines, lead the jet of jet pipe, straight tube bend pipe formation as the jet of arc pipe body and straight pipeline body composition and lead jet pipe etc.Soil pick-up is led the jet pipe cross-section of pipeline and be can be circle, square, prismatic, arc etc.The soil pick-up nozzle can be pore formula, short tube type and fine seam type etc.
Jet is led the soil pick-up nozzle on the jet pipe, can be located at jet as required and lead on any position of jet pipe body, adapts to crosswise jet direction and the spray angle that requires to constitute.Here the crosswise jet of saying, be meant that the soil pick-up nozzle can lead any one following current crosswise jet successively on any direction of jet pipe inboard outside solid space at jet, this crosswise jet can carry out on same space plane, also can not carry out on same space plane.
During work, the soil pick-up nozzle is crosswise jet forward successively, can lead the jet pipe both sides at jet and form negative pressure space, impel large-scale flue gas pollutant to pour into negative pressure space, carry injection by the soil pick-up jet again near the soil pick-up jet and pool unified exhaust airstream, and then discharge through discharge duct, this exhaust airstream does not advance jet source generation utensil, pollutes jet source generation utensil never.
What more than say is soil pick-up nozzle crosswise jet scheme, retell second kind below, be that the soil pick-up nozzle is concentrated ejection schemes, this scheme is with soil pick-up nozzle crosswise jet scheme, points to a place in the soil pick-up jet expansion direction set that different is in this programme, and the soil pick-up nozzle is concentrated a place to spray and converged the air-flow that forms, be the exhaust airstream of jet suction air engine, equally, this exhaust airstream does not advance jet source generation utensil, definitely can not pollute jet source generation utensil.
Point to a place in the soil pick-up jet expansion direction set, being meant that the soil pick-up nozzle can be concentrated points to jet and leads any one of the outside, jet pipe inboard solid space, all soil pick-up nozzles can be concentrated injection on same space plane, also can not concentrate on same space plane and spray.
During work, the soil pick-up nozzle is concentrated and is pointed out place injection, can lead the jet pipe both sides at jet and form negative pressure space, impel large-scale flue gas pollutant to pour into negative pressure space, near the soil pick-up jet, carry by the soil pick-up jet again and concentrate a place to spray to converge and become unified exhaust airstream, discharge through discharge duct again.
In order to strengthen the suction effect, above-mentioned two schemes can add the blowdown nozzle, and blowdown jet expansion direction is pointed to soil pick-up nozzle crosswise jet or concentrated to spray and converge the air flow direction that forms.The blowdown jet of blowdown nozzle ejection merge and drives the soil pick-up jet and the flue gas pollutant that carries mobile.The blowdown nozzle entrance can be directly be communicated with jet source generation utensil, also can lead jet pipe and intervalve is communicated with jet source generation utensil by jet.The blowdown nozzle can be located at jet and lead on the jet pipe, also can not be located at jet leads on the jet pipe, be not located at jet and lead two kinds of forms of branch again on the jet pipe, a kind of is independent installation, inlet directly or by the jet source input pipe is communicated with jet source generation utensil altogether, and a kind of is to lead jet pipe by intervalve with jet to be communicated with.
The blowdown nozzle can only be established a nozzle, also can constitute combined type blowdown nozzle by several nozzles.The blowdown nozzle is advisable with short tube, but also can adopt other forms as required, as pore, narrow slit, be provided with the ring pipe of pore or narrow slit and by several multi-form hybrid blowdown nozzles that constitute etc.
Blowdown nozzle and soil pick-up nozzle can spray on a space plane and converge, and also can not spray on the same space plane and converge.In a jet suction air engine, if what adopt is same fluid jet source, then blowdown jet expansion bore should be bigger than soil pick-up jet expansion bore, with the pollutant that guarantees that the blowdown jet can have enough mechanical energies to merge and drive the soil pick-up jet and carry, if in a jet suction air engine, use different fluid jet sources, as air stream and current, make the soil pick-up nozzle ejection go out air-spray, make the blowdown nozzle ejection go out jet spray, then the blowdown nozzle diameter just need not design too much.
Be provided with the jet suction air engine of blowdown nozzle, its soil pick-up nozzle no matter be successively crosswise jet or concentrate a place to spray, during work, the soil pick-up jet of soil pick-up nozzle ejection is absolutely different with the blowdown jet direction of blowdown nozzle ejection, the soil pick-up nozzle is led jet pipe horizontal or oblique laterally (tiltedly horizontal and contrary blowdown jet is tiltedly horizontal to comprise the dirty jet of in-line arrangement) by jet and is faced toward the injection of blowdown jet, and the blowdown nozzle is only done simple vertical injection of pointing to the discharge duct inlet.Like this, in soil pick-up nozzle and the common injection of blowdown nozzle, can jet lead the jet pipe both sides and near the wider more strong negative pressure space of formation, impel flue gas pollutant in larger scope to pour into negative pressure space, near the soil pick-up jet, give the blowdown jet by drive of soil pick-up jet and injection again, be discharged from again through the discharge duct inlet by the drive of blowdown jet then.Because the blowdown jet has bigger mechanical energy, the exhaust airstream pressure after converging is increased, speed increases.Thereby its penetration capacity is just strong.Like this, if the filtration, purification facility is housed,, flue gas pollutant will be filtered effectively as filter screen filter cloth active carbon etc. at discharge duct inlet.
Above-mentioned soil pick-up nozzle is crosswise jet and concentrate a place to spray two kinds of schemes successively, no matter be provided with the blowdown nozzle or do not establish the blowdown nozzle, also step-up jet can be set.
On the jet suction air engine of no blowdown nozzle, step-up jet can be located at soil pick-up nozzle crosswise jet or concentrate a place to spray and on the gas channel that converges successively, the afterburning jet of step-up jet ejection, the flow direction is intersected with the soil pick-up nozzle or is concentrated the soil pick-up jet that ejects to converge the air flow direction that forms, can be in the same way, also can be not in the same way; In the same way, the air-flow that converges of its afterburning jet and soil pick-up jet merges together, can replenish and increase the mechanical energy that converges air-flow of soil pick-up jet; Various flows to, afterburning jet can change the flow direction that converges air-flow of soil pick-up jet earlier, and then merges and make this converge stream pressure in the converging air-flow of soil pick-up jet and speed increases.
Be provided with on the jet suction air engine of blowdown nozzle, step-up jet is located on the blowdown jet expansion injection direction, promptly is located on the blowdown fluidic channel or blowdown jet and soil pick-up jet converge on the gas channel that forms.Be located on the blowdown fluidic channel, its afterburning jet and merges in the blowdown jet with the blowdown jet in the same way, and the blowdown jet pressure is pushed the speed increase.Step-up jet is located at the blowdown jet and the soil pick-up jet converges on the gas channel that forms, and its afterburning jet can be in the same way with this air-flow that converges, also can be not in the same way; In the same way, its afterburning jet merges in this air-flow that converges, and its pressure is increased, and speed increases; Not not in the same way, its afterburning jet can change this air flow direction that converges earlier, and then merge in this converge air-flow and its pressure pushed the speed increase.
Step-up jet can also be directly arranged in jet leads on the jet pipe, and it is identical with the step-up jet architectural characteristic of above-mentioned two kinds of installation forms to be located at the step-up jet architectural characteristic that jet leads on the jet pipe.
In a word, which kind of mounting structure form no matter, its step-up jet outlet injection direction all is directly to point to the discharge duct inlet indirectly, and the afterburning jet of step-up jet ejection merges in exhaust airstream, and exhaust airstream pressure is increased, and speed increases.
Step-up jet is the same with the blowdown nozzle, can adopt multiple multi-form, as straight short tube, curved spool, ring pipe, conical pipe, pore, narrow slit, and the combined type step-up jet that constitutes by several forms etc., have suitable being located on the blowdown fluidic channel of annular step-up jet of pore.Step-up jet inlet can be directly and the connection of jet source generation utensil, also can lead jet pipe and intervalve is followed the connection of jet source generation utensil by jet.
Both can strengthen the exhaust airstream penetration capacity by the step-up jet injection, and make flue gas pollutant obtain more effective filtration, and can strengthen suction effect and expansion space suction scope again.Therefore,, on a jet suction air engine, step-up jet can be do not established, one or more step-up jet can be established according to different requirements to filtration and suction effect suction scope.
Be provided with the jet suction air engine of step-up jet, the filtration, purification flue gas pollutant makes exhaust airstream clean more, so can prevent pollutant atmosphere more effectively more effectively.
For soil pick-up nozzle crosswise jet scheme, its jet is led jet pipe can also be provided with a plurality of (being advisable with square, straight tube shape), a plurality of jets are led jet pipe and are surrounded unified solid space, each jet is led soil pick-up nozzle on the jet pipe from following current crosswise jet successively in the middle of this solid space on every side, the soil pick-up jet of all soil pick-up nozzle ejection is all led the solid space interstage exchange that jet pipe surrounds at these a plurality of jets and is converged, and it promptly is the exhaust airstream of jet suction air engine that the air-flow that forms is converged in its interchange.Here the crosswise jet of saying of following current successively when being meant all soil pick-up nozzle crosswise jets, all flows to jet suction air engine discharge duct inlet by the preceding air-flow that then converges.
Lead nozzle structure for many jets, can also be provided with the blowdown nozzle, the blowdown nozzle can be located at its many jets and lead solid space one end that jet pipe surrounds, be that jet is led jet pipe group one end, its Way out passes through these many jets leads the solid space that jet pipe surrounds and points to jet suction air engine discharge duct inlet, do vertical injection, the soil pick-up nozzle that all jets are led on the jet pipe sprays and merges in the blowdown jet to the blowdown jet of central blowdown nozzle ejection every the space, flows to the discharge duct inlet again.
Many jets are led jet tube, its jet is led jet pipe can also overlap assembling (leading jet pipe with annular jet is advisable) at interval, make each jet lead jet pipe and form a level, the blowdown jet of blowdown nozzle ejection passes each jet successively and leads the space plane that jet pipe is encircled, and the soil pick-up nozzle on the different levels sprays round same blowdown jet.
Equally, this many jets are led nozzle structure, also can add step-up jet on its exhaust airstream passage, and the step-up jet architectural characteristic that its step-up jet architectural characteristic is led nozzle structure with above-mentioned non-many jets is identical.
The many jets that have the blowdown nozzle are led the jet suction air engine that sprays structure, can form the three-dimensional negative pressure space of deep and broad tubular during work, with the flue dust dirt poison gas at the far-reaching place of suction.The jet suction air engine of this structure uses in the especially suitable mine tunnel.
